Thanks for that Bill! My question is the Hantavirus something common to California. I’m crawling in attics all the time. When was the last California infection? Theo

Hantaviirus can kill This week the news of Hollywood actor Gene Hackman and his wife Betsy Arakawa were found deceased in their Santa Fe, New Mexico home. Toxicology and medical examiners reports that Betsy died of the Hantavirus several days before while Hackman died of heart disease. Both deceased persons were found by workers. Those who frequent our repeater sites are cautioned that the Hantavirus exists and may be fatal. The three sites most pronounced are Santa Ynez Peak, La Cumbre Cox Site, and Diablo Peak. The former SBARC La Vigia site was kept clean and all holes sealed. We have been careful not to overly stir up dust as the mentioned sites are the worse. Anyone with pulmonary issues should remain clear of the worst offending sites. Bill Talanian
From Wiki Orthohantavirus is a genus of viruses that includes all hantaviruses (family Hantaviridae) that cause disease in humans. Orthohantaviruses, hereafter referred to as hantaviruses, are naturally found primarily in rodents. In general, each hantavirus is carried by one rodent species and each rodent that carries a hantavirus carries one hantavirus species. Hantaviruses in their natural reservoirs usually cause an asymptomatic, persistent infection. In humans, however, hantaviruses cause two diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). HFRS is mainly caused by hantaviruses in Africa, Asia, and Europe, called Old World hantaviruses, and HPS is usually caused by hantaviruses in the Americas, called New World hantaviruses.
Hantaviruses are transmitted mainly through aerosols and droplets that contain rodent excretions, as well as through contaminated food, bites, and scratches. Environmental factors such as rainfall, temperature, and humidity influence transmission. Human-to-human transmission does not occur. HFRS is marked by kidney disease with kidney swelling, excess protein in urine, and blood in urine. The case fatality rate of HFRS varies from less than 1% to 15% depending on the virus. A mild form of HFRS often called nephropathia epidemica is often caused by Puumala virus and Dobrava-Belgrade virus. For HPS, initial symptoms are flu-like, with fever, headache, and muscle pain, followed by sudden respiratory failure. HPS has a much higher case fatality rate than HFRS, at 30–60%. For both HFRS and HPS, illness is the result of increased vascular permeability, decreased platelet count, and overreaction of the immune system.
Individual hantavirus particles (virions) are usually spherical and vary at 70–350 nanometers in diameter. They consist of the viral RNA, which is segmented into three parts and encased in helical nucleocapsids to form three ribonucleoprotein (RNP) complexes. Attached to each RNP is a viral RNA-dependent RNA polymerase (RdRp). RNPs are surrounded by a lipid envelope that has spike proteins emanating from its surface. Each part of the viral genome is single-stranded negative-sense RNA. The segments encode one protein each: RdRp, which performs transcription and replication of the genome, a glycoprotein precursor, which is formed into surface spikes on the envelope, and the N protein, which binds to and protects viral RNA. Some hantaviruses encode on the same segment as the N protein a non-structural protein that inhibits host interferon production.
Hantavirus replication begins by attaching to the surface of cells, usually vascular endothelial cells and macrophages. They then enter the cell and form vesicles to be transferred to endosomes and lysosomes. The viral envelope fuses with the membranes of endosomes and lysosomes, which empties the viral RNPs into the host cell's cytoplasm. RdRp then transcribes the viral genome to produce messenger RNA (mRNA) for translation by host ribosomes to produce viral proteins. RdRp also produces copies of the viral genome for progeny viruses. Old World hantavirus virions are constructed in the Golgi apparatus and obtain their envelope from the Golgi apparatus, before being transported to the cell membrane to leave the cell via exocytosis. New World hantavirus virions are constructed near the cell membrane, obtain their envelope from the cell membrane, and leave the cell by budding from its surface.
Hantaviruses were first discovered following the Korean War. During the war, HFRS was a common ailment in soldiers stationed near the Hantan river. In 1978 in South Korea, the first hantavirus was isolated, Hantaan virus, and was shown to be responsible for the outbreak during the war. Within a few years, other hantaviruses that cause HFRS were discovered throughout Eurasia. In 1982, the World Health Organization gave HFRS its name, and in 1987, hantaviruses were classified for the first time, and they collectively bear the name of Hantaan virus and the Hantan river. In 1993, an outbreak of HPS occurred in the Four Corners region in the United States, which led to the discovery of pathogenic New World hantaviruses and the second disease caused by hantaviruses. Since then, hantaviruses have been found not just in rodents but also shrews and bats.

Theo Like yourself our techs are really at dirty sites and I never can understand how site managers and government itself don't tackle the issue. Buildings can be made secure of infestation. Our La Vigia building was tight except for ants and lizards which we keep under control. Our original 220 machine at SYP was a total mess. The rodents ate all the wiring jackets under the chassis. There is often lots of evidence of rodent urine and droppings inside the racks and enclosures. It took me a couple of months to rebuild the repeater. Not sure what masking level to use. But at least hand washing and such would control one method of ingestion.

To add, if you know me, you know I go out to these desert cabins and stay in them and clean them up and that I have been doing this for /years/. Almost all of them have some type of Hantavirus warning either in them or outside. Almost all of them are provably not "rat proof". We even sweep these places out before we setup camp in them. Never got sick from it. I would even make jokes that I never got covid because all the hantavirus in me was like "GTFO, this body is mine!" I think although hantavirus is probably everywhere in those types of environments it is a very rare thing to contract. Kind of like the "Brain Eating Amoeba" that lives in hot springs and warm water (and probably your hot water pipes), it is everywhere in that environment, but exceedingly rare to get. That said, I did know a woman in the mid 90's that got Hanta, she was sick as hell for a few weeks and then fine afterwards, guess she got a bit lucky. Not saying that anyone is wrong to be concerned about it, just adding my experience with it. 73, Eric - KG6WXC On 3/13/25 22:43, Michael Ditmore via SBARC-list wrote:
